Nevermind... I saw this is already being considered.
Help! People keep hitting my DE storage. Please make hidden teslas act as lightning rods taking all the damage within a 3 or 4 block radius from their centre when a lightning spell is used in their vicinity.
The spell should still do splash damage at the base of the tesla to any CC troops and only the random lightning bolts that would've struck in the 3-4 block radius would be redirected to the tower.
Also, this could be used strategically to expose hidden teslas because if a lightning spell is cast near it, it would pop out of the ground exposing it's location.
It makes perfect sense and would solve a cheap ploy.
Thanks
PS Depending on how creative you want to be, you could reduce the damage the tesla takes from redirected lightning spells.
